Speaker 6

Thank you. Good afternoon, everyone, and thank you for joining us to discuss Soleno Therapeutics' Second Quarter 2025 Financial and Operating Results. Please note we'll be making certain forward-looking statements today. We refer you to Soleno's SEC filings for a discussion of the risks that may cause actual results to differ from the forward-looking statements. On the call with me today for Soleno are Anish Bhatnagar, Soleno's Chairman and Chief Executive Officer, Meredith Manning, Soleno's Chief Commercial Officer, and Jim Mackaness, Soleno's Chief Financial Officer. With that, I will now turn the call over to Anish.

Speaker 2

Thank you, Brian, and thank you, everyone, for joining us for our Second Quarter Financial Results Call. For those who follow us closely, you will know that we announced results for the second quarter ending June 30, 2025, on July 10. Therefore, many of you will be familiar with certain key metrics we'll be discussing today. With that said, I am very pleased to share our significant progress during the second quarter, highlighted by the commercial launch of VYKAT XR and commencement of treating people living with Prader-Willi Syndrome, or PWS. Meredith will review the company's commercialization progress to date, and Jim will cover the company's financial statements for the second quarter. We will then open the call for questions.

We achieved a major milestone for the PWS community and for Soleno Therapeutics in March when we launched VYKAT XR, the first FDA-approved medicine for the treatment of hyperphagia in adults and children four years of age and older with PWS. The approval of VYKAT XR was based on our comprehensive clinical development program, in which participants received double-blind and/or open-label VYKAT XR for a mean duration of 3.3 years. Primary evidence of efficacy came from a 16-week randomized withdrawal phase III, multicenter, double-blind placebo-controlled trial. Following FDA approval on March 26, VYKAT XR was available on April 14, ahead of plan. We've been extremely pleased with the initial reception and demand from the PWS community, which we believe speaks to the urgent need for an FDA-approved therapy to treat the hallmark feature of PWS, which is hyperphagia.

As we announced at that time, concurrent with product availability, prescriptions of VYKAT XR had been delivered to the first individuals living with PWS. Since that time, we have seen steady growth in both patient starts and unique prescribers. Total net revenue was $32.7 million in the second quarter, which in part reflects underlying demand for the drug, but also the significant efforts of our experienced commercial team, whose launch outreach efforts to patients, physicians, and payers set the stage for a strong and successful launch. As Meredith will describe in a moment, we have made steady progress with both commercial and government payers. We continue to engage with payers to ensure that they understand the severe complications and high unmet need associated with PWS and the inherent value proposition that VYKAT XR offers.

Establishing broad payer reimbursement is among our highest priorities going forward, and the compelling efficacy and safety data from our clinical trial program is clearly resonating. I would like to once again recognize the substantial contributions of the entire PWS community, including study participants and their families, the study investigators, and study site team members, as well as the two major PWS advocacy organizations, the Foundation for Prader-Willi Research and the Prader-Willi Syndrome Association USA. I would also like to thank the Soleno team members who worked so tirelessly to get us to this point. I would now like to provide a brief update on our activities in support of potential approval of DCCR in Europe. As you know, we market DCCR in the U.S. as VYKAT XR. PWS is a global disease that impacts hundreds of thousands of patients all over the world.

In an effort to make DCCR available to as many of these patients as possible, in parallel with our U.S. commercial launch, we have continued to make progress along regulatory pathways in other geographies, the most important of which is the EU. As we have stated previously, Europe also has a high unmet need among patients with PWS. Based on widely cited prevalence data, it is estimated that approximately 9,000 patients living with PWS in the EU fall in the UK. We have conducted market research with many PWS experts, patient advocacy leaders, care home executives, etc., where we have confirmed the prevalence numbers. Today, in most major markets in the EU, early diagnosis is common. Our research suggests that there is significant structured care for people living with PWS across Europe, with variations that will impact our go-to-market strategy by country.

Additionally, as with the U.S., the PWS community has strong thought leader support, and patient care is often concentrated around centers of excellence, even more so than in the U.S. In May, we were pleased to announce the submission and EMA validation of our marketing authorization application. Gaining approval to market DCCR in the EU would represent a meaningful expansion of our commercial market and remains a priority for us while we continue to progress our U.S. launch. I will now turn the call over to Meredith to provide an update on the launch. Meredith?

Speaker 1

Thank you, Anish, and good afternoon, everyone. As Anish previously mentioned, we are still early in our early phase of launch, and the response from both families and providers has been exceptionally encouraging. This tells us that our outreach, whether to caregivers, individuals with PWS, physicians, centers of excellence, payers, or advocacy groups, is truly resonating. Our disciplined execution and strong, clear messaging are helping us to build clinical conviction in the field. Taken together, these factors reinforce our confidence in the significant potential ahead. At this point, I would like to provide an update on the key performance indicators that we believe are helpful in tracking our progress. The first of these is patient start forms. As we announced in our preliminary results press release on July 10, we received 646 patient start forms from launch through June 30.

A vast majority of people who have started treatment, as expected, are younger, so that's between 4 and 26 years of age. However, a majority of these individuals are older than what we saw in the clinical trial C601, which was approximately 13.5 years. The second key performance indicator is the number of prescribers. From launch through June 30, that number is 295 unique prescribers. More than a third of the top 300 prescribers, who are the primary prescribers for approximately 2,000 patients, have written prescriptions, and we are very heartened to see a large number of start forms coming from prescribers who we did not expect to see writing start forms this early in our launch.

We believe the launch momentum and positive results directly reflect the success of our strategic launch efforts, initiatives that targeted pediatric and adult endocrinologists, geneticists, and psychiatrists who directly treat or influence a substantial portion of our addressable market. Our field force is prioritizing deep engagement with top-tier providers, each of whom treats multiple individuals with PWS, not only to further strengthen their experience and confidence with VYKAT XR, but also because these key clinicians play a pivotal role in influencing practice patterns and the broader adoption of new therapies within the PWS community. At the same time, we are increasingly encouraged by the strong response from physicians beyond this core group. This demonstrates not only growing awareness of VYKAT XR, but also expanding recognition of the therapeutic need to treat hyperphagia. The third performance indicator is payer policies.

As Anish mentioned, securing broad coverage for VYKAT XR is a core focus for us and is fundamental to the success of our launch. We have seen rapid and broad coverage surpassing recent rare disease launches, with approximately 33% of all insured lives now covered, representing just over 100 million lives covered in the United States. We are encouraged with the payer coverage policies established for VYKAT XR to date, including several from major insurers. It is worth highlighting that we are receiving coverage across all channels: commercial, Medicaid, and Medicare. To see such broad coverage so early in the launch is outstanding. These positive outcomes are a direct result of our proactive engagement, efforts that enabled payers to move quickly in recognizing the value of VYKAT XR and the urgency of addressing PWS-related hyperphagia.

The coverage decisions we have seen so far demonstrate that payers recognize the seriousness of PWS, understand the unique challenges of hyperphagia, and appreciate the meaningful value VYKAT XR delivers. I will now turn the call over to Jim for a review of the company's financial statements for the second quarter.

Speaker 8

Thank you, Meredith. We used $12.6 million of cash in operating activities during the three months ended June 30, 2025, and had $293.8 million of cash, cash equivalents, and marketable securities at the end of the quarter. Subsequent to the quarter end, we raised an additional $230 million of gross proceeds through an underwritten offering of our common stock, bringing our total pro forma cash balance following the financing to more than $500 million. This balance sheet strength ensures that we are sufficiently well-capitalized to execute on an effective U.S. launch of VYKAT XR and become cash flow positive, while in parallel progressing towards regulatory approvals and commercialization, either on a standalone basis or with partners in Europe and other geographies. Turning now to a few income statement items. Total net revenue for the second quarter ended June 30, 2025, was $32.7 million.

As VYKAT XR was approved in March of this year, the company generated no revenue in the second quarter ended June 30, 2024. Cost of goods sold was $0.7 million for the second quarter ended June 30, 2025. Please note that prior to the FDA approval, costs associated with manufacturing VYKAT XR were expensed as research and development expenses. As such, a portion of the cost of goods sold during the period included inventory at zero cost. Going forward, as we continue to sell VYKAT XR, we will deplete our zero-cost inventory and replenish it with at-cost inventory, and consequently, cost of goods sold as a percentage of revenue will increase.

Research and development expense for the second quarter ended June 30, 2025, was $9.1 million, which includes $2.4 million of non-cash stock-based compensation, compared to $12.3 million, which includes $2.7 million of non-cash stock-based compensation for the same period of 2024. The cadence of our research and development expenditures fluctuates depending upon the state of our clinical programs, timing of manufacturing, and other projects as we've moved through submission, approval, and now preparation for commercialization. Selling, general, and administrative expense for the second quarter ended June 30, 2025, was $28.2 million, which includes $7.3 million of non-cash stock-based compensation, compared to $10.9 million, which includes $4.5 million of non-cash stock-based compensation for the same period of 2024. The increase reflects our ongoing investment in additional personnel and new programs to support the VYKAT XR commercial launch and in support of our increased business activity.

Total other income, net, was $1.8 million for the three months ended June 30, 2025, compared to total other net income of $3.0 million in the same period of 2024. Net loss was approximately $4.7 million or $0.09 per basic and diluted share for the second quarter ended June 30, 2025, and $21.9 million or $0.57 per basic and diluted share for the same period in 2024. This concludes the financial overview, and I'll now turn the call back over to Anish for closing remarks. Anish?

Speaker 2

Thank you, Jim. In closing, while we are still early in the launch of VYKAT XR, we are pleased with the trajectory we're on. In the second quarter, we saw extraordinary momentum in the number of start forms, patients on active drug, number of patients on paid drug, and lives covered. While we're not able to share details at this time since we are far from a steady state, we continue to be encouraged that VYKAT XR is a groundbreaking therapy, and we believe it will soon be the standard of care for people living with PWS-related hyperphagia. With that, we'll now open the call to questions. Operator?

Speaker 7

Thank you. Ladies and gentlemen, we will now begin the question and answer session. Should you have a question, please press * followed by the 1 on your touch-tone phone. You will hear a prompt that your hand has been raised. Should you wish to decline from the polling process, please press * followed by the 2. If you are using a speaker phone, please lift the handset before pressing any keys. Your first question comes from Yasmin Rahimi with Piper Sandler. Your line is now open.

Good afternoon, team. Thank you so much for all the updates. I guess many of our clients were wondering if you could comment on how you see sort of the monthly scripts in July compared to the earlier months, and how you think it will change going into the remainder of August and September. I appreciate any color around that. Also, maybe one second one to squeeze in is, what is sort of the time to fill currently, and how do you think it would change over time? I'll jump back in the queue.

Speaker 2

Okay, thanks, Yasmin. I'll take the July question. As you know, we're not addressing data after the end of the quarter on this call. What I can tell you is that we have confidence that VYKAT XR is on its way to being the standard of care for people living with PWS. It is going to be a therapy that's going to be meaningful, and it's going to be something that PWS patients are going to be on for a long time to come. Meredith, I'll let you address the time to fill question.

Speaker 1

Yeah, thank you. Thanks, Yasmin, for the question. I think with regard to time to fill and something that we've mentioned in the past is it takes a while for the payer policies to come in and have a steady state. While we're very pleased and super encouraged with the 33% coverage live, you know, we still expect policies to come in and for that to grow. We've seen pretty rapid turnaround time based on the fact that we do have very strong policies, favorable policies coming in, and we have that 33% coverage. As more policies come in, the turnaround time could potentially slow. Hopefully, as we move into the later months, you know, after a full year, we're looking at reaching a steady state.

Something that we're shooting for that we've seen in other rare disease or other therapeutic areas, around approximately 30 days of turnaround time is pretty standard.

Thank you so much.

Speaker 7

Your next question comes from Rai Forseth with Guggenheim. Your line is now open.

Hi, this is Rai from DovJits team. Thanks for taking our questions. Are there any emerging pain points during the patient start form process that you see as addressable in the next couple of quarters? Our second question is, how are early compliance trends tracking?

Speaker 2

On the pain points front, as you know, this is a very strong start. I mean, 646 patient starts in the first quarter is a very large number. We try to track things like seasonality, holidays, vacay, summer holidays, things like that. This is the first drug launch for hyperphagia, so we don't know how it's going to be. It's hard for us to predict the pain points with the start forms. The next couple of quarters will be pretty educational, so we'll keep you posted on that. Your second question was?

Compliance.

Compliance.

Compliance.

Yeah, it's too early to tell, Rai, because we haven't seen that much data. What I can tell you is that discontinuation rates are substantially lower than what we saw even in clinical trials. As you may remember, in our trials, we've seen very high compliance rates, in part because some of the people living with PWS can also have obsessive-compulsive tendencies, and they tend to want to stay on drug as well. We don't expect that to change significantly, and it's certainly too early to tell from the data.

Thank you very much.

Speaker 7

Your next question comes from Kristen Kluska with Cantor Fitzgerald & Co. Your line is now open.

Speaker 3

Hi, everyone. Congrats on a very strong quarter. My first question, I just wanted to get a sense of what you're seeing on safety. You've obviously collected a lot of real-world evidence now. I know you're not commenting on specific revenue trends, but clearly, I think the Q2 numbers were a lot higher than a lot of us modeled and what the investment community was looking for. Can you just give us any broad sense of how we should be thinking about the rest of the year so people perhaps don't go over their skis either? Thank you.

Speaker 2

Sure. Thanks, Kristen. Thanks for the question. On the safety side, as many of you, I'm sure, know, monitoring for safety data in the post-marketing setting is quite different from clinical trial settings. One typically relies on reports from caregivers or healthcare providers, and the patients that you're treating are also often not as controlled and may have more comorbidities, et cetera. We are pretty early in the launch, but that said, I can tell you that we have not seen anything in the post-marketing setting that is different from the clinical trial setting. There are no new safety signals. Once again, just to reiterate, what we have seen with the discontinuation rates at this time are substantially lower than what we have seen in the clinical trials. Jim, I'll let you take the revenue question.

Speaker 8

Sure. Yes. Hi, Kristen. As you know, there are quite a number of moving parts between the start form and ultimately the revenue. I think what we saw was the fact that everything seemed to be clicking very, very well out of the gate. That's excellent. We're obviously sort of mindful of maybe things normalizing over the next couple of quarters. At the moment, it just seems to be a very strong start with everything all coming together. Good momentum out of Q2.

Speaker 3

Thank you.

Speaker 7

Your next question comes from Tyler Van Buren with TD Cowen. Your line is now open.

Hey, guys. Thanks very much, and congratulations on the tremendous progress made during the quarter. Regarding the $33 million of VYKAT XR sales for the quarter, can you help us understand to what extent there was an initial patient bolus or stocking in this number? I think you mentioned that commercially, you're seeing older patients than the 13.5 years in the trial. Does that mean on average that these commercial patients are heavier in weight, above that 61 kilograms, and higher than that average price of $466,000 estimated based upon that?

Speaker 2

Thanks, Tyler. Jim, you want to take the bolus stocking question?

Speaker 8

Yeah, so specifically to the stocking question, Tyler, we, as you know, we have one distribution partner, Panther. They have been managing their business, I'd say, very astutely. They order weekly from us. They obviously do carry a little bit of inventory, probably 7 to 10 days, but we've not really seen anything that was out of the norm. They've just been a very repetitive once-a-week stocking proposition from us, and that's continued. I don't think there's any anomalies there. I think on the bolus question, we do think there was a fantastic set of start forms coming in in Q2. I think we've commented before, hard to imagine that that will continue linearly going forward, if you like. There'll be some moderation there. Everything at the moment seems to indicate a very strong launch going forward.

Speaker 2

Tyler, to your question about patient weight, as you correctly pointed out, the patients that we're seeing, the majority of them are above the average age in C601, which is more than 13.5 years. I think it's a reasonable assumption that they are heavier as well.

Thank you.

Speaker 7

Your next question comes from James MacKaness with Stifel. Your line is now open.

Hey, thanks so much for taking my question, and congrats on the quarter. Just one from us. Just curious, you know, these patients and start forms you're seeing, obviously a great start. Is this all kind of coming? Are these patients on sort of like their normal cadence of visiting doctors, or are these kind of patients, you know, calling in and trying to get in kind of off cycle? Just curious if you have any color on that dynamic and kind of on that more broadly. All the kind of cylinders seem to be firing here. Curious what is the rate limiter here kind of going forward if there's any that's obvious to you. Thanks so much.

Speaker 2

Meredith, go ahead.

Speaker 1

Yeah, happy to take that. You know, it's been really nice to get out in the field and be with our field team and also meet with many of the clinicians. We're seeing both, to answer your question, both patients who were very proactive as they were anticipating the launch of VYKAT XR, getting some of their appointments set up within an early timeframe. We're also seeing that some of the PWS experts are very busy with the launch, and therefore it is taking time to get some of the other patients coming in. I think something that we're very excited to see is many of these clinics did not have a set PWS clinic day prior to launch.

As we're seeing the groundwork being laid across these various different clinics, they are setting up their PWS clinic days, and we feel like that will allow for a little bit more steady patient visits and patient cycle to come in. We're still seeing good, significant opportunity ahead with the way that the landscape is really, you know, measuring out their process and their logistics.

Speaker 7

Your next question comes from Leland Gershow with Oppenheimer. Your line is now open.

Hi, good afternoon, guys, and thanks for the update and tremendous progress. I wanted to ask, you know, maybe a little bit in connection with the last question. Patients with PWS come at different levels of severity, like in all diseases. Wondering if you're seeing any pattern where perhaps the more severe patients are the ones who are getting VYKAT XR earlier, as in, you know, Q2 and currently. If we should maybe think about, you know, a broader uptake as, you know, physicians become more familiar with the drug. I also want to ask with respect to Europe. I know that's probably going to be in next year, but, you know, you're sort of touching profitability here on the U.S. business.

Wondering if you could just comment on what could be maybe a more efficient launch in Europe with respect to OpEx and how that may affect your thoughts on profitability and cash flow going forward. Thanks.

Speaker 2

Sure. Thanks, Leland. In terms of severity, we don't actually collect that information actively. What we see is a diagnosis of Prader-Willi Syndrome and presence of hyperphagia is sort of on label and the age of four years, and that patient would be on label. We don't get that level of detail. I suspect there's probably a combination of things happening. One is the idea that if there are severe patients, there's probably physicians who are calling them in earlier and getting them on drug. There's definitely an element of more motivated families, likely with younger kids, who are also pushing their way to getting therapy earlier.

We think this phenomenon of a lot of the non-KOL prescribers may well be the idea that the KOL practices are so full that some of these more motivated families are going to peripheral providers, their local endos, et cetera, and getting prescriptions from there. In terms of the EU business and OpEx, Jim, you want to take that?

Speaker 8

Yeah, sure. I think, Leland, you said, that goes back to the fact that we have the $500 million of balance sheet strength. It allows us the optionality when we're looking at Europe. We mentioned partners along the way, but we now also have the ability, if we wish, to continue to do it on our own. We do think it's a concentrated market. Some of the ways that rare diseases are addressed within the European countries do present sort of smaller call points than even in the U.S. We've still got to work out the details on exactly the size of the sales force, the commercial team that would be needed if we do go on our own. We think it's manageable. As I said, we just point back to the $500 million because it gives us that option to do it if we choose.

All right, thank you.

Speaker 7

Your next question comes from Brian Scorney with Baird. Your line is now open.

Hey, good afternoon, and thanks for taking my question. Congrats on, in my entire career, being the first company to have a sequentially down operating expenditures into the first quarter of launch. Very impressive. To that point, Jim, I'm just wondering, looking at the OpEx, if this is a fair go-forward number to model for the U.S. business, and you know, you only, it says that operationally spent $12.5 million in cash. I'm just wondering if I look at just the income statement, you did $32.7 million in sales. It was about $40 million in OpEx. If I back out stock-based comp, that's $10 million less. I would have thought that we would actually be operationally cash flow positive. What's in the cash flow from operations here that's not kind of summing up with the income statement?

Speaker 8

Go ahead, Jim. I'm not sure I understand the tail end of that question, but Brian, let me provide the color that we've, I think we've provided in the past. Our cash OpEx, I think we've mentioned in the past, we think about $120 to $130 million for this year. We may find that there's a reason to increase that a little bit, but there wouldn't be much more than $140 million. That would just be doing things, like I said, putting some early initiatives in Europe, as we've mentioned. There's also some life cycle management stuff we might fire up as well. Still very well managed for 2025. If we go into 2026, that'll increment. I think, again, we mentioned it probably going north of $150 million, but it certainly will be managed, not too much aggressively above that.

A lot depends on the size of the Europe commercial footprint and if we decide to go along alone. I think to your point, you just got to layer the revenues from the launch. We've sort of said, that's why we've commented in the past. If we think what we've referred to as a modestly successful, I would suggest Q2 is exceeding that. If we have a modestly successful launch, that's how we see ourselves getting to cash flow positive in somewhere in the near term. Hopefully, that provides you the guidance you're looking for.

Yep, that's perfect. Thanks, Jim.

Speaker 7

Your next question comes from Yale Jen with Cantor Fitzgerald & Co. Your line is now open.

Good afternoon, and thanks for taking the questions and add my congrats as well. Just a little bit in terms of the revenue breakdowns. In terms of the patients that the titrating phase income, the cells versus the maintenance cells, the number is quite different. I'm just curious whether most of the patients in this quarter are already the patients in the trial, so they are actually immediately moved to the maintenance, or there are many more newer patients that are actually in the earlier titration stage? Thanks.

Speaker 2

Yep, thanks, Yale. As you may remember, only about 60 patients were on the long-term study in the U.S. The rest were in the UK. If you look at 646 start forms, that's a pretty small fraction of it. As we've said in the past, virtually all of them will be on our own commercial drug at this time. It's fair to say that in this quarter, a number of patients are still in the titration phase, or at least part of the quarter they were in the titration phase.

Okay, great. Maybe just one more question. In terms of any breakdown in terms of payers between government and the commercial, thanks.

Too early to tell, Yale. I think we're not quite at a steady state yet, but we'll just remind you of the actual split in the population. It's about a third commercial, a third Medicare, and a third Medicaid. We don't have numbers to provide for this quarter because of all the moving parts.

Okay, great. Thanks a lot. Again, congrats and great quarter.

Thanks, Yale.

Speaker 7

Ladies and gentlemen, as a reminder, should you have a question, please press *1. Your next question comes from Ram Selvaraju with H.C. Wainwright. Your line is now open.

Hi, this is Jade on for Ram. Congrats on that first commercial quarter. You're doing great. First, have you seen any reluctance on the part of your prescribers to deploy in patients who have PWS and are also diagnosed with diabetes?

Speaker 2

You know, we don't get sort of real-time information on these things, but I think it would be reasonable for a payer to be, for a provider to be hesitant if someone has uncontrolled diabetes. If it's diabetes that is controlled, then there's no reason to be reluctant to use DCCR. Of course, you need to be careful and do all the appropriate monitoring per the label, but the drug can certainly be used in patients who have type 2 diabetes.

Okay, great. Just as a follow-up, looking to the future, are you thinking about expanding your portfolio beyond VYKAT XR? If so, would this potentially include opportunistic in-licensing and in what areas?

Yeah, I think it's fair to say that as of today, we are laser-focused on the launch of VYKAT XR, and we don't want to deviate from that. I think in the long term, it's fair to say that we would, as a company, need to diversify from just VYKAT. You know, we will look for opportunities that are likely adjacent to where we are today. That is certainly not something we would do in the very short term.

Makes sense. All right, thank you.

Thank you.

Speaker 7

There are no further questions at this time. I will now turn the call over to Anish for closing remarks.

Speaker 2

Thank you all again for calling in, and we look forward to talking to you at the end of the next quarter.

Speaker 7

Ladies and gentlemen, this concludes your conference call for today. We thank you for participating and ask that you please disconnect your lines.
